　　Function members provide some functionality for manipulating data in classes, including methods, properties, constructors and destructors, operators, and indexers.methods are functions related to a class, which can be instance methods or static

It's like a method for the person who implementsLike fields for callersAttributes can be seen as an intelligent field, and properties are the extension of fields and methods.One of the principles of object-oriented is data encapsulation, so the
